Just to the middle of May, we thought we were still some distance away from the hot weather was hit by a surprise, according to the weather forecast issued by the weather station, 17-19, the highest temperature in most areas in the north are above 35 degrees. And in the face of hot weather, friends with cardiovascular disease should pay attention. Summer heat more sudden death of heart attack cardiovascular patients can not be taken lightly Many people believe that the cold winter is prone to heart attack, which is due to low temperatures will make the body’s adrenaline-like secretion increases, vasoconstriction, blood viscosity increased, if the occurrence of blood clots blocking the coronary arteries, it will trigger an acute heart attack. With the advent of summer, many patients with coronary heart disease are relieved to think that they have passed the dangerous period, but in fact, as the temperature rises in summer, the weather is sultry and the humidity in the air rises, which can lead to angina or heart attack in patients with coronary heart disease. This is because due to the high temperature environment, the body’s metabolism will be significantly accelerated, the body in order to dissipate heat, will make the surface of the blood vessels expansion, more blood circulation to the surface, the heart and other organs of blood supply will be relatively reduced, for the original coronary heart disease myocardial ischemia, but also easy to trigger myocardial infarction. In addition, in order to dissipate heat, the heart beat frequency accelerates, the heart contraction intensity increases, the heart beat bleeding increases, such as in the room temperature reaches 35 ℃, the heart beat bleeding will increase by 50% to 70%, for the original heart disease, the heart often can not bear the extra burden and cause an acute heart attack, or even sudden death. Secondly, high temperature will cause internal environmental disorders, increased sympathetic nerve tension, accelerated heart rhythm and coronary artery contraction, thus increasing the burden on the heart; again, sweating in summer, the body’s water evaporates in large quantities through sweat, and blood viscosity rises, making it easy for platelet aggregation and thrombosis to occur, triggering myocardial infarction; finally, “psychological cold “is also the cause of the high incidence of cardiovascular disease in summer, hot weather, people’s mood is also prone to irritability, tension, coupled with the summer nights, dry and hot weather, sleep quality decline, easily lead to sympathetic excitement, so that the heart’s oxygen consumption increased, if coupled with factors such as overexertion, the risk of morbidity is even greater. Safe summer cardiovascular patients 10 attention: In order to summer heat weather attention to prevent myocardial infarction, safe summer, cardiovascular disease heat, especially the elderly, need to pay attention to do these 10: (a) static and dynamic appropriate activity exercise is appropriate in the early morning cooler, do not exercise in the hot sun. Activity intensity should be moderate, not too long, in order to reduce the load on the heart, reduce myocardial oxygen consumption, to prevent myocardial ischemic attack; when the weather is hot and muggy, the humidity in the air, outdoor activities should be reduced. (B) Anti-deployment cooling When outdoor activities or labor should wear a sun hat and have enough water to prevent the peripheral vasodilatation, insufficient blood volume and reduced coronary artery blood supply, myocardial ischemia and induced heart attack. When the weather is hot, indoor air conditioning can be turned on, but the degree should not be too low, not too long, generally about 25 degrees is appropriate, so that not only can regulate the indoor temperature, but also reduce the humidity of indoor air, improve the content of oxygen in the air. (C) get up and live in an orderly manner Due to the heat, sleep late at night, do not get up too early in the morning, and rest properly at noon to supplement the lack of sleep. (D) Adjust the medication Under the guidance of a specialist, make some appropriate adjustments to the medication usually taken for the treatment of cardiovascular disease, and carry anti-cardiac pain medication such as nitroglycerin or isoamyl nitrite with you if you travel. (E) light diet Summer people’s digestive tract function is reduced, appetite decline, diet should be light, eat more fresh vegetables, fruits, black fungus, soy products, etc., can eat some lean meat, fish, try to eat less too greasy or high-fat food. Meals should not be too salty, too much salt will make the blood pressure rise. (F) pay attention to hydration Do not wait until you are thirsty to drink water, to drink more cool water, timely replenishment of water, you can also drink some light salt water. It is best to drink some boiled water half an hour before going to bed, waking up in the middle of the night and early in the morning after waking up. If the conditions can often drink such as green bean soup, lotus seed soup, lily soup, chrysanthemum tea, lotus tea and other beverages, both to replenish water, but also to clear the heat, less caffeinated drinks. (G) stabilize the emotions of the human central nervous system directs everything, when over-excited, nervous, especially when overjoyed, sad and angry, due to the stress response of the central nervous system, can make small arteries vasoconstriction, resulting in a rise in blood pressure, heart rate, myocardial contraction enhanced, so that patients with coronary heart disease ischemia, hypoxia, thereby triggering heart pain or myocardial infarction. Every effort should be made to avoid adverse stimuli such as excessive tension, excitement, anxiety and depression, and to avoid stimulating activities such as stock trading and marijuana rubbing. Only psychological balance can be physiological balance, normal function of the organs, smooth blood flow, will be away from the threat of heart attack. (H) avoid smoking and limit alcohol research shows that the incidence of coronary heart disease in smokers is three times higher than non-smokers. In addition, often drink strong alcohol, can lead to heart disease and hyperlipidemia due to alcohol poisoning. Excessive ethanol can also increase the oxygen consumption of the heart and aggravate coronary heart disease. You can drink some wine appropriately, but not more than 1 ml per day. (ix) Smooth bowel movements Constipation and excessive bowel movements can cause a sharp increase in myocardial oxygen consumption, which can easily lead to cardiac pain. To develop the habit of regular bowel movements, eat more coarse fiber vegetables and fruits, such as celery, bananas, etc., appropriate consumption of coarse grains is also conducive to laxative. (J) weight control Many chronic diseases are related to obesity, such as hypertension, hyperlipidemia, diabetes, etc. . We must pay attention to weight control and reduce the total heat energy of food. Coronary heart patients should not be too full, too full not only easily lead to body fat, and can directly compress the heart, increase the burden on the heart, leading to cardiovascular spasm, and even the occurrence of cardiac pain and acute myocardial infarction.
